American researchers said that mice raised in a sterile environment or given antibiotics at birth lack a common gut bacteria that seems to prevent food allergies.
This bacterium, called Clostridia, seems to reduce the possibility of rats being allergic to peanuts. Researchers hope to explore whether this is also true for humans.
At the same time, according to a report published in the Proceedings of the National Academy of Sciences in the United States, researchers have found that giving probiotics containing Clostridium spp after the rats grow up may reverse allergies.
Cathryn Nagler, professor of food allergy at the University of Chicago and senior research author, said: “Such as overuse of antibiotics, high-fat diets, caesarean section, removal of common pathogens, and even formula feeding, will affect our Microbes evolved together."
Nagle said: "From our research results, it can be known that this will increase the risk of food allergy."
